“I asked Microsoftâ€™s Jeff Woolsey, Principle Group Program Manager for Hyper-V, what the problem was and he responded that memory overcommitment results in a significant performance hit if the memory is fully utilised and that even VMware (whose ESX hypervisor does have this functionality) advises against itâ€™s use in production environments. I can see that itâ€™s not a huge factor in server consolidation exercises, but for VDI scenarios (using the new RDS functionality), it could have made a significant difference in consolidation ratios.”

Of course, if SLAT allows improved performance, then other platforms will also benefit from it (although not necessarily to the same degree) but, if VDI really is a feasible technology solution (I have my doubts and consider it a “significant niche” solution), I’m sure Microsoft will come up with something for the third incarnation of Hyper-V.
